氧化锆陶瓷有时被称为“陶瓷钢”，由于其优异的性能而引起了人们的广泛兴趣。然而，希望在提高陶瓷磨削工艺的经济性的同时保持表面质量。采用激光/磨削复合工艺对氧化锆陶瓷进行磨削加工，在复合工艺中，氧化锆陶瓷在磨削前先用连续激光进行辐照。从磨削力和磨削能量、材料去除率和损伤形成机理等方面研究了激光/磨削复合加工氧化锆陶瓷的可行性。结果表明，激光辐照可以诱导产生横向裂纹，这有助于材料去除，并阻止裂纹进一步扩展到基体。磨削试验结果表明，与传统磨削方法相比，磨削力和磨削能量显著降低。在这项工作中的地面上的破碎区，犁条纹，和很少碎片的组合表明，脆性模式和韧性模式的复合材料去除机制。
Zirconia ceramics which are sometimes called “ceramic steel” have gained significant interest because of their excellent properties. However, it is desired to maintain the surface quality while increasing the economics of ceramics grinding process. A hybrid laser/grinding (HLG) process was utilized to grind zirconia ceramics which was irradiated with continuous wave laser before grinding in the hybrid process. The feasibility of hybrid laser/grinding of zirconia ceramics was investigated in terms of grinding force and energy, material removal, and damage formation mechanisms. The results show that laser irradiation can induce lateral cracks, which can help material removal and prevent further crack propagating into the base. The results of grinding tests indicate that grinding force and energy decrease significantly as compared with conventional grinding of ceramics. The combinations of the fractured area, the plowing striations, and seldom debris on the ground surfaces in this work indicate the combined material removal mechanism of both brittle mode and ductile mode.
